The bolivar, like Venezuelaâs economy, is trapped in a downward spiral. Within Venezuela the effects of the economic chaos are seen at the supermarket, where empty shelves are a constant reminder of the economic dysfunction that has come to define South Americaâs fifth largest economy.
In optics, chromatic aberration (CA, also called achromatism, chromatic distortion, and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.n some circumstances it is possible to correct some of the effects of chromatic aberration in digital post-processing. However, in real-world circumstances, chromatic aberration results in permanent loss of some image detail.
A refracting telescope which has been freed from the effects of chromatic aberration is called achromatic. The secondary spectrum is very commonly confounded with the chromatic aberration of higher order. The observer should first determine whether the chromatic aberration is corrected.
